I am curious to see what the result is from this. I've seen a lot of seaplane operations around Europe and the States (C206 & C208), both in coastal waters and in harbours.
Have seen permission granted in Barcelona Port and obviously in Hamburg on the river they use the seaplane for tourism on a daily basis.
So, why aren't seaplanes used so much in the UK, i am interested to see where this thread goes.
And on the C208, yes the seaplane operations does result in corrosion, and the likes of turbine blades are susceptible, thus that should be taken into account. But aside from that, they seem to do pretty well in choppy water, and quite easily get permissions.
